RANGEFINDING TIPS
Rangefinding binoculars work by emitting a brief pulse of light
aimed at a target object. Distance is determined by the amount
of time taken for the light to emit and return to the laser’s
internal receiver. A laser’s ability to read range can be affected
by many things—mostly relating to the target objects.
• Light colors will usually reflect better than dark ones.
• Be aware that snow, rain, and fog will have adverse effects
on ranging ability.
• Shiny, reflective surfaces will usually reflect better than dull,
textured surfaces. Animal hair will not reflect as well as a
hard surface.
• Ranging under cloud cover can improve laser performance
compared to bright sunny conditions.
• Solid objects, such as a rock, will reflect better than bushes.
• Flat surfaces perpendicular to the laser pulse will reflect
better than curved surfaces or surfaces angled in relation to
laser pulse.
• Ranging over water can sometimes cause false reflections
and readings.
• At longer distances, large objects will be easier to range
than small objects.
• If you are having difficulty ranging an animal or object, try
ranging a different nearby object, or use the Scan feature to pan
back and forth while watching for changes in range number.
